Figure 3.

The lipid profiles of bacteria after 24 h (A) and 48 h (B) exposure to propolis. The m/z values of features were assigned to singly protonated ions (M+H)+ or (M+Na)+ with an allowed 0.05 m/z mass difference. Only statistically significantly changed features were annotated. The molecular features present in propolis extract were removed from test samples. X-axis values correspond to the fold change observed for annotated lipids, which were grouped in classes (different colors). Values above zero represent upregulation, while below zero downregulation. MG, monoacylglycerols; DG, diacylglycerols; TG, triacylglycerols; PG, diacylglycerophosphoglycerols; PE, diacylglycerophosphoethanolamines; PI, diacylglycerophosphoinositols; Lyso-GP, monoacylglycerophosphoglycerols; Lyso-PE, monoacylglycerolphosphoethanolamines; MK, menaquinones.
